Stereoelectroencephalography (SEEG) is widely performed on individuals with medically refractory epilepsy for whom invasive seizure localization is desired. Despite increasing adoption in many centers across the world, no standardized electrode naming convention exists, generating confusion among both clinical and research teams.
We have developed a novel nomenclature, named the Standardized Electrode Nomenclature for SEEG Applications system. Concise, unique, informative, and unambiguous labels provide information about entry point, deep targets, and relationships between electrodes. Inter-rater agreement was evaluated by comparing original electrode names from 10 randomly sampled cases (including 136 electrodes) with those prospectively assigned by four additional blinded raters.
The Standardized Electrode Nomenclature for SEEG Application system was prospectively implemented in 40 consecutive patients undergoing SEEG monitoring at our institution, creating unique electrode names in all cases, and facilitating implantation design, SEEG recording and mapping interpretation, and treatment planning among neurosurgeons, neurologists, and neurophysiologists. The inter-rater percent agreement for electrode names among two neurosurgeons, two epilepsy neurologists, and one neurosurgical fellow was 97.5%.
This standardized naming convention, Standardized Electrode Nomenclature for SEEG Application, provides a simple, concise, reproducible, and informative method for specifying the target(s) and relative position of each SEEG electrode in each patient, allowing for successful sharing of information in both the clinical and research settings. General adoption of this nomenclature could pave the way for improved communication and collaboration between institutions.
立体脑电图（SEEG）广泛应用于药物难治性癫痫患者，这些患者需要进行侵袭性癫痫灶定位。尽管在世界上许多中心的应用越来越多，但目前尚无标准化的电极命名约定，这给临床和研究团队都带来了困惑。
我们开发了一种新的命名法，命名为立体脑电图应用标准化电极命名系统。简洁、独特、信息丰富且明确的标签提供了有关进入点、深部靶点以及电极之间关系的信息。通过比较 10 例随机抽样病例（包括 136 个电极）的原始电极名称与另外 4 名盲法评分者前瞻性分配的电极名称，评估了组内一致性。
立体脑电图应用标准化电极命名系统前瞻性地应用于我院 40 例连续接受立体脑电图监测的患者，在所有病例中均创建了独特的电极名称，便于神经外科医生、神经科医生和神经生理学家进行植入物设计、立体脑电图记录和映射解释以及治疗计划。两名神经外科医生、两名癫痫神经科医生和一名神经外科研究员之间电极名称的组内一致性百分比为 97.5%。
这种标准化命名约定——立体脑电图应用标准化电极命名，为指定每位患者每个立体脑电图电极的目标和相对位置提供了一种简单、简洁、可重复且信息量丰富的方法，便于在临床和研究环境中成功共享信息。这种命名法的广泛应用可以为机构之间的沟通和协作提供便利。
